Airframe control bearings are manufactured to meet the stringent demands of aircraft control and aerospace applications. Manufactured in accordance with U.S. military specifications (MIL-SPEC) and made from stainless steel or other metals or materials, airframe control bearings are resistant to corrosion, shock, and temperature extremes. Airframe control bearings are available in numerous styles and sizes to meet required speeds and loads.
Due to their precision manufacture and durability, airframe control bearings have also been used in a wide variety of applications outside the aircraft industry, including medical devices, robotics, and materials handling systems – virtually any application requiring a high load capability and oscillatory and/or slow rotation. Airframe control bearings can be heat-treated or sealed against chemicals or extreme temperatures. Coatings and plating such as dry film, thick or thin dense chrome, zinc nickel, and silver are also available. Lubrication options are designed to support devices that operate at high and low temperature extremes. Bearing Service stocks several common airframe control bearings and has the ability to source hard to find product.
Tapered roller bearings have tapered inner and outer ring raceways between which tapered rollers are arranged, optimizing rolling conditions. Tapered roller bearings are utilized in applications where there is a combination of radial and axial (thrust) loads. Tapered roller bearings are separable and have the following components: outer ring, inner ring, and roller assembly (containing the rollers and a cage). The non-separable inner ring and roller assembly is called the “cone”, and the outer ring is called the “cup”. Internal clearance is established during mounting by the axial position of the cone relative to the cup.
It is important to note that tapered roller bearings are predominantly sold as individual components. Therefore it is important to know the part number of both the cup and the cone, as they will most often differ and there are often many cup/ cone combinations available. While feasible to replace only the cup or the cone when replacing a tapered roller bearing, it is not recommended as it greatly decreases bearing life.
Tapered roller bearings are used in numerous applications and are capable of high loads and speeds. The predominant use is in any wheel application, where the tapered roller bearings are normally arranged in back to back pairs where they support axial and radial loads in both directions. Tapered roller bearings are available in a wide array of both inch and metric sizes.
A ball bearing is a term referring to a type of bearing which utilizes steel balls to maintain the separation between the moving parts of the bearing. The purpose of a ball bearing is to reduce rotational friction and support load. Deep groove ball bearings, also known as radial ball bearings, are used in a variety of applications. They are the most popular of all rolling bearings, capable of very high speeds and available in a wide array of sizes. Ball Bearings utilize point contact to reduce friction and are available in many styles. These include single row ball bearings, self-aligning ball bearings, angular contact ball bearings and double row ball bearings.
Ball bearings are offered with many performance enhancing options, such as with metal shields or rubber seals to minimize contamination and retain lubrication. Compared to other bearing types, the ball bearing is the least expensive, primarily because of the low cost of producing the balls used in the bearing. Bearing Service Inc. represents numerous ball bearing manufacturers and maintains stock at each branch location as well as our distribution center.
